WMG's Tucson Water Rainwater Harvesting Rebate educational sessions will include a brief tour of water harvesting features on site, an introduction to rainwater harvesting, information about the rebates, and a design process. Please bring a map and / or drawings of your site, with measurements of any impervious surfaces (roof, patio, driveway, street, etc.) you wish to harvest from. The more information you can bring, the better, including where water flows on the property. Online mapping resources will be provided in your confirmation email.
